Bar Graph Indications
Signal Strength:
Viewed with the cover removed (refer to the “Removing the Cover” paragraph in Section 3),
this display consists of one yellow and four green LEDs arranged in a bar graph. It indicates
the signal strength at which the 7845CZ is receiving the local cell. The display is intended as
an installation aid for determining a suitable mounting location. Refer to the “Selecting a
Radio Installation Site” paragraph in Section 4 for an explanation of its use.
Power-Up:
During power-up, the bar graph LEDs are used to monitor radio initialization, and are read
from right to left. Refer to the “Initial Power-Up Sequence” paragraph in Section 4 for
details.
Registration:
The bar graph display also monitors the radio’s registration progress. Refer to the
“Registering the Radio” paragraph in Section 6 for detailed information.
